It's because you don't have PostgreSQL installed. The LitDB instructions say, among other things, "Make sure that you have a PostgreSQL database running and that you have permissions to create tables in that database".
The LitDB installation instructions are quite brief, which is probably fine for someone who knows Django already, but you're in for a rough ride. What operating system are you running? In Debian/Ubuntu you can install postgresql with "apt install postgresql". Are you executing manage.py as root?
